RAZOR STROPPEB.

Application filed December 7, 1925. Serial No. 73,612.

To aZZ whom it may concern:

Be it known that I, LooMrs N. MoFALL, a citizen of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Razor Stroppers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in stropping devices for razor blades.

The blades employed in connection with what is generally known as safety razors are so constructed that they cannot be honed or stropped without first being secured in some specially constructed holder. For this purpose a variety of holders have been invented and it is to this class that my present invention belongs.

It is the object of this invention to produce a holder, for blades of safety razors, which shall be of simple and substantial construction which can be cheaply made and which will be especially well adapted for the purpose for which it is intended.

My improved razor blade holder, briefly described, consists of two cylindrical tubular members one of whichfits inside of the other with a sliding fit. Each of these tubular members has a part out from the material thereof, at one end, and bent outwardly in a radial direction producing two jaws that can be moved towards or away from each other by rotating the tubular members relative to each other. One of these jaws has two spaced plugs that are adapted to engage elongated openings in the other jaw and to pass through openings in the razor blades. A locking means is provided for holding the jaws in operative position.

Having now briefly described my invention, I shall proceed to describe one specific embodiment thereof in detail and for this purpose reference will be had to the accompanying drawing in which the preferred construction has been illustrated and in which:

Fig. 1 is a perspective view of my improved holder showing the same in closed operative position;

Fig. 2 is a view similar to that illustrated in Figure 1 but showing the holder in open or inoperative position;

Fig. 3 is a transverse section taken on line 33, Fig. 1; and, r

Fig. t is a section similar to that in Fig. 3 but showing a single edge blade in place between the jaws.

My improved holder consists of two tubular members 1 and 2 of unequal diameters. The smaller, or member 2, has an outside diameter that is substantially the same as the inside diameter of member 150 that when the two members are assembled in the manner shown they can be rotated and moved longitudinally with respect to each other. Tube 2 has been cut longitudinally along line 2 and transversely for a short distance from the end. The part of the tube thus cut loose is bent outwardly into a radial direction so to form a radial jaw A. The inner end of this aw is bent back so as to form a hook 4:.

The outer, or tube 1, is likewise out longitudinally along the line 5 and transversely along line 6 and the part thus cut loose is bent outwardly in a radial direction so as to form ajaw B. The outer end of jaw B is bent backwardly so as to form a hook 7. It ,is now apparent, when reference is' had to the drawing, that by rotating the tubes 1 and 2 relative to each other, thejaws A and B can be moved towards or away from each other, such movement being a rotary movement about the axis of the tubes. The length of the out along line 5. is longer than the jaw B by, at least, the length of the hook t so that the jaw A may be pulled inwardly a sufficient distance to permit the end of the hook 4 to pass the inner end 8 of the aw B and this movement will at the same time permit the end 9 of the jaw A to pass by the end of the hook member 7. When the jaws are moved into substantially parallel. position and then moved longitudinally until the hooks 4 and 7 engage the respective adjacent ends or" the jaws B and A, the parts assume the operative position shown in Fig. 1. As the razor blades that are to be held are double edged and provided with two holes intermediate their ends. I have provided the jaw B with two plugs 10 and jaw A with two corresponding elongated slots '11 that are adapted to receive the plugs 10. lVhen the razor blade C is to be clamped in place, it is laid onto the jaw 13 in such a position that the plugs 10 ext-end through the openings after which the parts are moved to the position shown in Fig. 1, in which position the blade is firmly held in such a position that it can be honed and stropped. In order to prevent the members 1 and 2 from being separated, a knurled ring 12 is fastened to the outer end of the inner member 2. A similar knurled ring 13 is secured to the outer member near the inner end of the jaw B so as to improve the appearance and add to the rigidity of the construction.

When the holder is to be used with single edge blades that have no holes for the reception of the plugs 10, these may be omitted and the blade clamped as shown in Fig. l in which the single edge blade has been indicated by numeral 1% and its stiffened reenforced edge by numeral 15. l have shown the jaws provided with locking hooks l and 7 and consider that these are the most satisfactory. It is obvious, however, that other equivalent means may be substituted and I therefore do not desire to be limited to this exact locking means unless required by the state of the art.

Having now described my invention, what I claim as new is:

1. A razor blade holder comprising, in combination, a pair of concentric tubular members which have a limited rotary and longitudinal movement with respect to each other and a jaw extending radially from each member and means for locking said jaws in operative position.

2. A razor blade holder comprising, in combination, two concentric cylindrical members, one of which is tubular, said members being adapted to have relative rotary and longitudinal movement, a radially extending jaw connected to each of said members, said jaws having their adjacent surfaces adapted to be moved into substantially parallel planes for the purpose of clamping a razor blade and means for locking said jaws in clamping position.

3. A razor blade holder, comprising two cylindrical members one of which is tubular and the other of which is positioned therein, the outer member having a longitudinal slot extending inwardly from one end thereof, a jaw secured to the outer member and having a substantially radial surface, a similar jaw secured to the inner member and extending outwardly through the slot whereby said jaws may be moved towards or away from each other by a relative rotary movement of the cylindrical members and means for clamping said jaws in operative position.

4:. A razor blade holder comprising, in combination, two tubular members one of which is located within the other, the outer member having a slot extending inwardly from one end thereof and a jaw extending radially adjacent one side of said slot, the inner member having a jaw member extending radially therefrom and projecting through said slot, said jaws being relatively movable into and out of clamping position and means for locking them in clamping position.

5. A razor blade holder comprising, in combination, two tubular members one of which is located within the other, the outer member having a slot extending inwardly from one end thereof and a jaw extending radially adjacent one side of said slot, the inner member having a jaw member extending radially therefrom and projecting through said slot, said aws being relatively movable into and out of clamping position and means for locking them in clamping position, said locking means comprising a hook member on one jaw adapted to engage V the other jaw.

6. A razor blade holder comprising, in combination, two tubular members one of which is located within the other, the outer member having a slot extending inwardly from one end thereof and a jaw extending radially adjacent one side of said slot, the inner member having a jaw member extending radially therefrom and projecting through said slot, said aws being relatively movable into and out of clamping position and means for locking them in clamping position, said locking means comprising a hook member carried by each jaw and adapted to engage the other jaw.

In testimony whereof I afiix my signa ture.
